Izumo-taisha (出雲大社, Izumo Grand Shrine?, also Izumo Ōyashiro) is one of the most ancient and important Shinto shrines in Japan. No record gives the date of establishment. Located in Izumo, Shimane Prefecture, it is home to two major festivals. It is dedicated to the god Ōkuninushi (Ōkuninushi-no-mikoto), famous as the Shinto deity of marriage.

A style of architecture, taisha-zukuri, takes its name from the main hall of Izumo-taisha. That hall, and the attached buildings, were designated National Treasures of Japan in 1952. According to tradition, the hall was previously much taller than presently. The discovery in the year 2000 of the remains of enormous pillars has lent credence to this.

Several other buildings in the shrine compound are on the list of Important Cultural Properties of Japan.

Origins

According to the two oldest chronicles of Japan, the Kojiki and Nihon Shoki, when Ninigi-no-Mikoto, grandson of the Sun Goddess Amaterasu, descended from the heavens, the god Ōkuninushi granted his country to Ninigi-no-Mikoto. Amaterasu was much pleased by this action and she presented Izumo-taisha to Ōkuninushi.

At one time, the Japanese islands were controlled from Izumo, according to Shinto myths. Izumo, known as the realm of gods or the land of myths, is Izumo-taisha's province. Its main structure was originally constructed to glorify the great achievement of Ōkuninushi, considered the creator of Japan. Ōkuninushi was devoted to the building of the nation, in which he shared many joys and sorrows with the ancestors of the land. In addition to being the savior, Ōkuninushi is considered the guardian god and god of happiness, as well as the god who establishes good relationships.

According to the Nihon Shoki, the sun goddess Amaterasu said, "From now on, my descendants shall administer the affairs of state. You shall cast a spell of establishing good relationship over people to lead them a happy life. I will build your residence with colossal columns and thick and broad planks in the same architectural style as mine and name it Amenohisu-no-miya." The other gods were gathered and ordered by Amaterasu to build the grand palace at the foot of Mt. Uga.

There is no knowledge of exactly when Izumo-taisha was built, but a record compiled around 950 (Heian period) describes the shrine as the highest building, reaching approximately 48 meters, which exceeds in height the 45 meter-tall temple that enshrined the Great Image of Buddha, Tōdai-ji. This was due to early Shinto cosmology, when the people believed the gods (kami) were above the human world and belonged to the most extraordinary and majestic parts of nature. Therefore, Izumo-taisha could have been an attempt to create a place for the kami that would be above humans.

According to Kojiki, the legendary stories of old Japan, and Nihon Shoki, the chronicles of old Japan, Izumo-taisha was considered the largest wooden structure in Japan when it was originally constructed. Before being known as Izumo Ōyashiro or Izumo-taisha, the shrine was known as Okami-no-miya in Izumo, Itsukashinokami-no-miya, Kizuki-no-Oyashiro, Kizuki-no-miya, or Iwakumanoso-no-miya.

Evidence of the original Grand Shrine has been found. For example, part of one of the pillars for the structure was found: three cedar trees with a three-meter diameter at its base. It is on display at the shrine. Although there is not much early evidence one can see when visiting, there is a shop just before the main entrance that has a smaller scale model of the original main structure made by local college students.

History

During the Kamakura era, around 1200, the main structure was reduced in size. Then in 1744, the shrine was reconstructed to the present size of 24 meters high and 11 meters square at its base.

In the 18th and 19th centuries, as travel became more common in Japan, the shrine became a central place of pilgrimage.

Since the shrine spirit was settled in the inner shrine in 1744, it has been relocated three times for renovation of the inner shrine, using a traditional ceremony. The relocations took place in 1809, 1881, and 1953.

From 1871 through 1946, the Izumo-taisha was officially designated one of the Kanpei-taisha (官幣大社), meaning that it stood in the first rank of government supported shrines.

In April 2008, the spirit was moved to temporary housing in the front shrine of Izumo-taisha in preparation for the Heisei-era renovations. Izumo-taisha's inner shrine was opened to the public for the first time in 60 years in the summer of 2008.

Architecture

The main structure of Izumo Oyashiro was built in the Taisha style, the oldest style of building shrines. An impressive sized gable-entrance structure is built for the main structure, which gave the name of The Great Shrine or The Grand Shrine. The main hall (honden) bears an enormous chigi (scissor-shaped finials at the front and back ends of the roof). A Japanese architecture book states, “In plan, the present Main Shrine resembles that of the Daijoe Shoden, built for the accession of each new emperor. The main shrine at Izumo is thought, therefore, to preserve a floor plan characteristic of ancient domestic architecture” (Nishi & Hozumi, 1985, p.41). From the view of architectures, the original height of the main structure of Izumo Taisha makes it difficult to study the historical building styles and methods. However, what is known is that from the construction of a building as big as the main structure, major problems were presented. Because of this, structural and stylistic changes occurred each time the main structure was rebuilt, which caused the outer form to be less reflective of the original construction of the main structure. Although the outside of the structure changed with each reconstruction, the floor plan remained virtually unchanged. The layout consists of eight support pillars arranged so that the inside is divided into four sections and causes the entrance to be off-centered. A significant characteristic that is common among most shrines is the symmetrical design, making the main structure of Izumo-taisha peculiar for its asymmetrical floor plan. The main structure was built more like a home rather than a shrine which suggests that between the people and kami there was a less formal relationship than at other shrines.

Kaguraden

Izumo-taisha's Kaguraden (神楽殿 Kagura hall) was first built in 1776 by the Senge family, Izumo Kokusō, or governor of Izumo, as a grand hall for performance of traditional rituals. It was rebuilt in 1981 to commemorate the centennial of the foundation of the Izumo Oyashiro-kyo order.

Traditional prayer by Izumo Kokuso, wedding ceremonies of believers, and the performances of sacred dance to ancient Japanese music involve the Oracle with 240 mats. Also worshipped with prayer is a frame with four dyed Chinese characters, meaning “the Oracle Filled with Aureole,” by Prince Arisugawa above the altar.

The Kagura-den features the largest shimenawa (sacred straw rope) in Japan; it is 13.5 meters long and weighs around 5 tons. The rope is one of the most easily recognized and distinctive features of Izumo-taisha.

Shōkokan

The Shōkokan (彰古館) consists of two floors. The first floor is the reception office for Kaguraden. The second floor consists of a museum for important items.

Some items in the museum are items designated as national treasure and important cultural assets, like jewelry, household articles, paintings, swords, and musical instruments.

Considered most important in Shōkokan are a set of Japan’s oldest wooden pestle and an igniting board and a small boat that was hollowed out of a piece of wood. The small boat was believed to have come from the upper stream of the Yoshino River, through the Seto Inland Sea, and to the Inasa Beach near Izumo-taisha.

Festivals

Festivals in Izumo are a time when the people gather around the god to fulfill their wish to live a happy life. One of the most important festivals in Izumo-taisha is the Imperial Festival held on May 14. Following the Imperial Festival is the Grand Festival on May 14 and 15.

Some other major festivals are January 1, Omike Festival; January 3, Fukumukae Festival; January 5, Beginning Sermon Festival; February 17, Kikoku (prayer for abundant crops) Festival; April 1, Kyoso Festival; June 1, Suzumidono Festival; and August 6–9 is Izumo Oyashiro-kyo Religion Festival. In October of the lunar calendar, a festival is held to welcome all the gods to Izumo Grand Shrine. It is believed that the gods gather at Izumo Shrine in October to discuss the coming year’s marriages, deaths, and births. For this reason, people around the Izumo area call October kamiarizuki ("the month with gods"), but the rest of Japan calls October kannazuki'' ("the month without gods").

Administrator's Family

The descendants of Amenohohi-no-mikoto, the second son of the sun goddess and ancestor of the imperial family, have been, in the name of Izumo Kokuso or governor of Izumo, taking over rituals because when Izumo-taisha was founded Amenohohi-no-mikoto rendered service to Okuninushi-no-kami. Takatoshi Senge, the 83rd-generation Izumo Kokuso, died in February 2002 at the age of 89. He was chosen to be the chief priest of Izumo-taisha in 1947.
